[GRASS-user] map algebra logical operators on DCELL rasters not admitted? maybe docs should outline it

Doing a logical operation with a DCELL raster within an if(x,a) statement produces an error: "Incorrect argument types to function bitand()". This doesn't seem to be described inside the docs, is it? When the if() function is described it only states its behaviour in case of NULL, 0 or

Re: [GRASS-user] add superscript to units on a legend

Hi, I had the same problem some time ago, and just kept the "^" in µg/m^3 because i didn't find superscript format nor in d.text (or the gui to add text) neither in ps.map... But maybe in your case you can use mg/ha to avoid the ^? Cheers, Vero 2015-10-18 21:41 GMT-03:00 Davies, Kalu

Re: [GRASS-user] map algebra logical operators on DCELL rasters not admitted? maybe docs should outline it

That's what disappointed my client (and me) Glynn: why integer yes and not floats? Is it a technical limitation or there's a ratio behind it? Anyway did I miss something from the docs? I couldn't find it. Why do you that I'm confusing the operators? I've always talked about logical operators...
